PLOW.

SPECIFICATION forming part of Letters Patent No. 224,455, dated February10, 1880.

. Application filed March 1,1879. I

To all whom it may concern:

Be it known that -I, ELBRIDGE Gr. MAT- THEws, of Le Sank, in the countyof Stearns and State of Minnesota, have invented certain new and usefulImprovements in Flows; and I do hereby declare that the following is afull, clear, and exact description of the in vention, which will enableothers skilled in the art to which it appertains to make and use thesame, reference 7 being had to the ac.- companying drawings, and toletters of reference marked thereon, which form a part of thisspecification.

Figure l of the drawings is a representation of a side elevation of myplow, and Fig. 2 is a plan view of the same.

This invention has relation to plows; and it consists in theimprovements in the construction of the same hereinafter fullydescribed, and particularly pointed out in the claims.

In carrying out my invention I mount the plow-frame upon suitableriding-wheels, both of which are secured to a crank-axle so that theymay be adjusted either to ride in the furrow or upon the unturned land,as may be required in operating the plow. I also pro,- vide two plows,one of which is a right-hand and the other a left-hand plow, and these Ioperate with racks and pinions, so that they may be raised and loweredalternately at will, for the purpose of causing the furrows to-.al-.ways he turned in one direction by simply traversing the field back andforth.

To hold the plows in the proper positions I- ment is effected throughperforations in its shank and a screw and nut which clamp it against anarm upon the upper face -of the platform.

, Referring to the drawings, A designates the platform; B, thesupporting-wheels, and G. the crank-axle, carrying the adjustin g-diskD. A vertical block, E, is provided with ways in which the adjListing-racks F work. The teeth of pinions G G, one on each side of theblock E, engage with the teeth of the racks F. Perforated disks H I aresecured to the shafts J J, on which the pinions G are fixed, andstayrods K, provided with hooks, are used to hold the plows L L at anyposition to which they may be adjusted by inserting the hooks on said,I'ods into the perforations in the disks H I. I

A sliding arm, M, is employed to enter the perforations in the disk D,to hold the crankaxle G toits adjustment.

The guide-wheel N has a perforated shank, O, the latter being madevertically adjustable through the screw a, thumb-nut b, and arm P on theplatform A. The block E is extended V forward and a drivers seatism'ounted thereon.-

The plows L L are rightand left plows, and are to be alternatelyadjusted, so that the field may be traversed back and forth and thefurrows turned all in the same direction.

' The crank-axle O is to be adjusted through its disk D, to keep theaxle itself even, either when the wheel thereto attached is in thefurrow or upon the unturned land.

I claim-j- 1. In a plow, the combination of the crankaxle 0, having theperforated disk D, with the sliding arm M, substantially as and for thepurposes set forth. a

2. In a plow, the crank-axle 0, having the perforated disk D, with thesliding arm M, in

combination with the plows L L, secured to the racks F, working in waysin the block E,

and the pinions G G upon the shaft J, carrying the perforated disks H I,and the hooked rods K, substantially as and for the purposes ELBRIDGE G.MATTHEWS.
